Seattle Firm Aims to Harness Helium-3 from Solar Wind
By Editor • August 26, 2026 • 1 min read
A Seattle-based company is exploring the potential of helium-3, a rare isotope produced by the Sun, which escapes into the solar wind.
Over millennia, this wind has bombarded the Moon, embedding helium-3 into its surface due to the lack of protective atmosphere. Meteorite impacts occasionally mix this isotope slightly below the lunar regolith, presenting a unique opportunity for future lunar exploration.
